Measurements of the Absolute Branching Fraction of the Semileptonic Decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ and the Axial Charge of the $Ξ^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +685

Using $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected with the BESIII detector, we study the semileptonic decay $Ξ^{-} \to Λ e^{-} ν ˉ_{e}$ for the first time at an electron-…
